I just built gantry cnc router and am using mach3 with lazy cam.
I have 2 problems
1 the z axis motor jams at times causing it to lose it's reference to zero. It will also do it with the motor removed from the mill, turning with no load.
2 when using lazycam to make pockets, the program stops randomly. I get the following error
Unrecoverable Error in EndGLdraw1....Notify artsoft
I am new to this so any help is appreciated.
